MOIECE-WWEE FOE LINOTYPE-MACHINES.

To all whom it may conoe'm: Be it known that 1, Groves C. GLENN, acitizen of the United States, resid at Raleigh, in the county of Wakeand tate of North Carolina, have invented a new and usefulMhuthpiece-Wiper for Linotype-Machines, of which the following is aspecifistion.

The present invention relates to improvements in mouth piece wipers forlmotype machines, the primary olnect of the invention beingitheprovision of a reciprocatory wiper actuated from the'maincaxn shaft ofthe linotype machine and disposed towipe the mouth piece from the topdownward uponthe initial stroke to clear the horizonwhen the same lineis cast more than once,

the wiper will be operated once to each casting operation, thus cleaningthe vents of the mouth piece thoroughly between each castin operation.

ith the foregoing and 0t or objects in view which will appear as t edescription proceeds, the invention resides in the'combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of What is claimed without departing from the spirit of theinvention.

In the drawings--Fi ure 1 is a'plan view showing a portion of t e camshaft, mouth piece and mold disk and the adjacent portion of a linotypemachine with the present mouth piece wiper in operable relation thereto.Fig. 2 is 'an elevation taken from the main cam side thereof. Fig. 3 isa section taken on line 3-3 of Fig. 2. Fig. 4

is a perspective view of the wiper per cc. Fig. 5 is a cross sectionthrough the wiper showing the manner of securing the wip ng material inosition. Figs. 6 and 7 are detail views s owing the connection at theonce every revolution of the main cam shaft 1 and elevator cam 1, thecam 2 will actuate the wiper as will presently appear.

The shifter lever hub 3 is disposed in the usual manner between therespectivebear- Bpccitleattou ot Letters Patent. 5:1 Patented June 1Q,1913., I

wiper to the actuating shaft therefor. Fig.

ings Land 4:, while journaled in the bearings 4 and 12, carriedby theframe of the machine, is the shifter actuating rod or shaft 5.

Keyed upon the shaft 5 adjacent to the bearing 4, is a collar 6 which isprovided with the arm 7 having the outwardly projecting lug 8 which isdisposed in the path 4 to be engaged by the cam 2 once every revolutionof the shaft 1, the spring 9 being disposed upon the shaft 5 and-havingone and connected, as at 10, to the shaft while the other end isconnected, as at 11, to the been ing support 4. T he spring ,9 is sotensioned as to hold the lug 8 of the arm 7 downwardly upon the face ofthe cam 2 at all times, so that the rotation of the shaft 1 and theaction of the cam 2 upon the lug 8 of the arm 7 will impart a movementin opposition to the spring 9 so as to properly oscillate or reciprocatethe shaft 5 within its bearings and 12. v

The extreme outer end of the shaft 5 is reduced as at 5 for thereception of the wiper, carrying arm l3, the milled screw 14 beingemployed to retain the arm 13 upon the reduced end of the shaftb, butpermitthe arm 13 to have a certain play, such pla being limited by meansof the dovetail socket 15 and the dove-tail projection 16 carried by thereduced end 5 of the shaft 5. In order to impart. a spring tension tothe :arm 13, the spiral spring 17 is provided and has one end connectedto the shaft 5 as at 18, while the other end is seated within the notch19 of the arm 13.

Connected to the mold gear arm of the machine and fulcrumed at 2,0 isthe lever 21, which has connected to its free end a link 22, the upperend of which is in the path to f engage the arm 13 and thus provides aprecautionary device to prevent the wiper 2 245 to resilientl fromdropping in between the mouthpiece and the mold disk, or remaining thereshould the spring 9 give way. disk in moving toward the mouth piece willpress against the lower end of lever 21, which has a tendency to carrythe Wiper 24: up to its normal position.

"The Wiper 24 is connected to the armel-i by means of two screws 23,which are provided with springs being mounted upon the screwsand-interposed between-the adjacent faces of the arm 13 and the innerend of the wiper hold the wiper relatively to the arm 13. bus thesprings 25 add resiliency to the wiper when moved across and against thenipple or mouth piece 28 a and between the nipple and mold disk 29,

" wardly across the a 29 during both of usual construction. a l

The Wiper 24 is preferablymade from sheet metal and is provided with theinturned flanges 26 for the reception of the ,flexible strip 27, whichis the wiping material disposed in operable relation or adjacent to thenipple or mouth piece28 and is normally held in elevated position abovethe mouth piece, with its front end 27' so disposed as to readily'passithe mold disk the reciprocation of thewiper 24 downwardly acrossthe path of the mouth piece" and upwardly-"out of the way of the molddisk 29 between each casting operation. The mechanism for operating thewiper is so constructed and; timed as to move the wiper 24 downwardlyfrom the top of. the mouth piece or nipple.28 throughout the full lengthof the mouth piece and upsame during the movement of the mold disk 29away from and toward the mouth piece between each castoperatlon. rom theforegoing description, it will be seen that a, mouth piece wiperwhich isconstructed and arranged according to the present invention may beoperated to wipe the mouth piece of the metalmold box twice between thecasting of every slug, that is on a downward movement'and anupwardmovement thereof, thus er'mitting a close locking u ofthe mold disk withthe mouth prece'an preventing any back squirts, and as the wiping pad 27carries oil and graphite, the outer surface of the mouth. p 1ece ornipple is cleansed each reciprocat ion of the wiper and clearedof anymetal that has altndency to adhere to the outer surface of the mouthpiece.

By this construction of device, a better and more solid slug is secured,and one which will enable the ressman when lockmg up the forms to espthe slugs upon theirt .feet and thusmw ea more perfect prin.

The mold the adjusting nuts 23, the.

naled upon the, frame, a spring By removing the wiper actuating shaft 5away from'the delicate mechanism of the casting machine, it is evidentthat the movement of the wiper across. the mouth piece does not-in anyway aflect the casting or the shifter band, as is the usual practice inattaching mouth piece wipers and that therefore the tendency to jar themachine or the delicate parts thereof is prevented in a deviceconstructedand arranged according to the present invention.

What is claimed is: v

1. In a line casting machine, the combination with the main frame, amain shafh and a mouth-piece, of an oscillatory shaft jourfor impartingone-movement to the 0561 atory shaft,

an arm carried byisaid oscillatory shaft and operably connected to themain shaft, and

a wiper blade having a tension toward the mouth-piece and carried bysaid oscillatory shaft for reciprocation thereby. v

2; In a line castin machine, the combina tion with the main rame, a mainshaft, and a mouth-piece, of an oscillatory shaft journaled upon theframe, a spring for returning the oscillatory shaft, an arm carried byso said oscillatory shaft and operably connected to the main shaft, atensioned arm loosely connected to the outer end of said oscillatoryshaft, and capable of a dependently of the spring connectedto theoscillatory shaft and arm to cushion the movement transmitted from theshaft to the arm, a wiper blade, and a resilient connection between'thearm and blade vand exerting a tension upon the wiper blade toward themouth-piece.

3. In a line'casting machine, the combination with the main frame,ainain shaft, and a mouthpiece, of a wiper-mechanism for themouth-piece, comprising an oscillatory shaft journaled upon the frame, acam mounted upon the main shaft, a finger carried by the. oscillatoryshaft and disposed Within the path to be engaged by the cam, a springslight movement inupon 'the oscillatory shaft for moving the 114) an armshaft in opposition to the cam, loosely mounted upon the outer end ofthe oscillatory shaft, a spring connected to said arm and theoscillatryshaft to limit the movement of the and relative to the\osciloscillatory shaft, .21

latory shaft, 21 wiper blade, and a resilient.

connection between the arm and blade for retaining the blade undertension towardthe mouth piece.

In testimony that I claim the foregoing as my own, I have hereto alfixedmy signature in the presence of two witnesses.
